In the summer and autumn seasons, the flower buds of various fruit trees such as peach, plum, pear, apricot, apple, jujube and persimmon have differentiated. The accumulation of tree nutrients and the quality of flower bud differentiation are closely related to the yield and quality of fruit trees in the following year. Therefore, in addition to the normal soil, fertilizer, water management and pest control during this period, according to the different varieties, the pros and cons of the tree vigor, take some measures conducive to flower bud differentiation, in order to improve the yield and quality of fruit trees. 1, early fruit picking and fruit picking by stages For saplings or old and weak trees, early fruit harvesting should be carried out according to the specific conditions of tree vigor, so as to reduce the nutrient burden on the tree body, so as to facilitate restoration of vigor and promote flower bud differentiation. To adopt a method of fruit harvesting in stages for better-managed high-yield trees is beneficial to the restoration of tree potential. 2, timely ingenious root fertilizer The fruit consumes a lot of nutrients in the tree body and must be supplemented with nutrients in time to restore the tree vigor, ensure that there is sufficient nutrient supply for flower bud differentiation, improve the quality of flower buds, and increase the ability to withstand cold in winter. Generally, the strong trees are sprayed with a 0.2%~0.3% potassium dihydrogen phosphate solution or a mixture of 2%~3% superphosphate and 0.3% urea; 0.3%~0.5% urea solution is sprayed on the old and weak trees, each 7~ Spray 10 times a day, even spray 3 to 4 times. 3, appropriate water control to facilitate flower bud differentiation For fruit trees that undergo flower bud differentiation in May to October, such as apples, peaches, plums, pears, etc., after the fruit is picked, the liquid fertilizer is applied twice every 7 days, and the water is controlled until the color of the fruit leaves becomes light, and the leaves are slightly changed. The degree of micro cracking of the roll or topsoil. If the drought is too severe, it is necessary to spray water on the leaf surface or splash water on the surface, and control the water for 20 to 30 days. For trees with early results and prosperous trees with few results, the water control time should be longer. But should not be too long, otherwise it will affect the partial root or sun root. For the low-lying, poorly-drained mountain orchards or orchard with heavy soil, it is possible to perform partial root cutting at the early stage of flower bud differentiation, and to lightly root the roots of the fruit trees with shallow root distribution and open the soil around the roots of the roots. day. For fruit trees whose flower bud differentiation period is after October, pay attention to frost prevention, open the soil in the morning, cover soil and cover grass in the afternoon. For the low-lying, poorly-drained mountain orchards or orchard with heavy soil, it is possible to perform partial root cutting at the early stage of flower bud differentiation, and to lightly root the roots of the fruit trees with shallow root distribution and open the soil around the roots of the roots. day. For fruit trees whose flower bud differentiation period is after October, pay attention to frost prevention, open the soil in the morning, cover soil and cover grass in the afternoon. 4, spraying agent Spraying before the shoot stops can effectively control the growth of new shoots and promote the differentiation of the top buds into flower buds. After the fruits are harvested, paclobutrazol is used to control its growth, which can promote flower bud differentiation. Orally applied paclobutrazol, usually 15-30 grams per plant, after-effect up to 3 years. Spraying ethephon in autumn can control the growth of young trees and promote the development of short and middle branches, which is conducive to the formation of flower buds (used for unsuccessful saplings). 5, timely trim It is necessary to summer trim the trees of the initial results. Buds topping: Eradication of budded shoots in the canopy and competition buds under the clippings. When the new shoot reaches 40 centimeters, it will be picked up. Twigs Twisting branches: The method of pulling branches, hanging branches and supporting branches is adopted for erect growing fruit trees that grow more prosperously, and the angle of upright branches is increased; for leggy branches or prosperous branches, 180 degrees are to be reversed, but do not twist and cause the leggy. Branches turn into branches and ease the tree. Ring cutting: For Wang Changshu, depending on the situation, it can be cut on the side of the big side branch, upright branch or on the main trunk. The bark can not be peeled off, and it can reach deep to the xylem. Can also be used lead wire or thin wire binding, to yellow when the veins must be unfastened, this method is applied to thin tree species of fruit bark, such as apples, pears, peaches, plums, dates, persimmons, etc. Isopropyl Alcohol Recycling Machine Calstar® Solvent Recovery Machine Recyclable: washing solvent, acetic acid esters, halogenated hydrocarbons, three ethyl chloride, trichloroethylene, solvent oil, isopropyl alcohol, acetone, butanone and cyclohexanone, days that water, wash water gun, banana water, plate washer water, wash water network, wash water, white oil, hand washing water, diluent, washing water, ink cleaning agent, ethyl acetate, toluene, xylene, toluene three, four toluene, banana water, alcohol, ethanol, butanol, two glycol solvent waste and dirty etc..
